Potable Drinking Water
The Division of Environmental Health conducts plan reviews, permitting and final installation inspections for new and
modified private water wells. Education and regulation concerning private water wells help ensure a safe potable water
supply. This limits exposure to pathogens and reduces negative environmental impacts.
Private Water Well Installation
Before a private sewage disposal system can be installed, a State of Illinois, Illinois Department of Public Health,
Application for Permit to Construct, Modify or Abandon a Water Well and the $100.00 application fee payable to the
Illinois Department of Public Health must be submitted. If the proposed water well meets the requirements of the Illinois
Water Well Construction Code, the applicant will be granted a permit. It is then the responsibility of the applicant to give
48 hour notification to the Division of Environmental health prior to installation. After your well is installed, Your New Well
offers tips on keeping your well safe.
An estimated 400,000 private water wells in Illinois provide drinking water to approximately 1.3 million people. Each year,
many of these wells are abandoned when they are replaced with new wells or when homes are connected to community
water systems. An abandoned well can pose a health and safety hazard if it is improperly sealed or not sealed at all.
When abandoned wells are left open, children, animals or even adults can fall into them, causing injury or death. Also, an
abandoned well can serve as a route for contaminating groundwater.
The following information will help insure your abandoned well is properly sealed:
